Protection of the environment
General notes
H
Environmental note
Daimler's declared policy is one of
comprehensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in amanner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an
environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
R
operating conditionsofyour vehicle
R
your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R
avoid short trips as these increase fuel
consumption.
R
always make sure that the tire pressures
are correct.
R
do not carry any unnecessary weight.
R
remove roof racks once you no longer need
them.
R
aregularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R
always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R
do not depress the accelerator pedal when
startingthe engine.
R
do not warm up theenginewhen the vehicle
is stationary.
R
drive carefully and maintain asafe distance
from the vehicle in front.
R
avoid frequent, sudden acceleration and
braking.
R
change gear in good time and use each gear
only up to Ô of its maximum engine speed.
R
switch off the engine in stationary traffic.
R
keep an eye on the vehicle's fuel
consumption.
Environmental concerns and
recommendations
Wherever the operating instructions require
you to dispose of materials, first try to
regenerate or re-use them. Observe the
relevant environmental rules and regulations
when disposing of materials. In this way you
will help to protect the environment.

G
WARNING
If SRS is malfunctioning, child restraint
system componentsmay be triggered
unintentionally or might not be triggered at all
in the event of an accidentwith ahigh rate of
vehicle deceleration. There is an increased
risk of injury, possibly even fatal.
Have SRS checked and repairedimmediately
at aqualified specialist workshop.
SRS functionsare checked regularly when
you switchonthe ignition and when the
engineisrunning. Therefore, malfunctions
can be detected in good time.
The 6 SRS warninglamp in the instrument

Triggering of Emergency Tensioning
Devices and air bags
Duringthe firststageofacollision, the airbag
control unit evaluates important physical
datarelating to vehicle decelerationor
acceleration, suchas:
R
duration
R
direction
R
magnitude
Based on theevaluation of this data, theair
bag control unit pre-emptivelytriggersthe
Emergency Tensioning Deviceinthe first
stage.
If there is an evenhigher rateofvehicle
decelerationoracceleration in alongitudinal
direction, the front airbags are also deployed.
Your vehicle has adaptive, two-stagefront air
bags. The air bag control unit evaluates
vehicle deceleration or acceleration in the
eventofacollision. In the firstdeployment
stage, the frontair bag is filled with enough
propellantgas to reducethe risk of injuries.
The front air bag is fully deployed if asecond
deploymentthreshold is reached within afew
milliseconds.
The Emergency Tensioning Device and air bag
triggering thresholds are variable and are
adapted to the detected rate of deceleration
or acceleration of the vehicle. This process is
pre-emptive in nature. The triggering process
must take place in good time at the start of
the collision.
The rate of vehicle deceleration or
acceleration and the direction of the force are
essentially determined by:
R
the distribution of forces during the
collision
R
the collision angle
R
the deformation characteristics of the
vehicle
R
the characteristics of the object with which
the vehicle has collided
Factors that can only be seen and measured
after acollision has occurred do not play a
Occupant safety
41
Safety
Z
decisive role in the deployment of an air bag,
nor do they provide an indication of air bag
deployment.
The vehicle may be deformed significantly,
e.g. the hood or the fender,without an air bag
being deployed. This is the case if only parts
which are relatively easily deformed are
affected and the rate of deceleration is not
high. Conversely, air bags may be deployed
even though the vehicle suffers only minor
deformation. This is the case if, for example,
very rigid vehicle parts such as longitudinal
body members are hit, and sufficient
deceleration occurs as aresult.
i
The frontEmergencyTensioning Devices
can only be triggered if the seat belt
tongues on the frontseats are correctly
engaged in the seat belt buckles.
i
Not all air bags are deployed in an
accident. The differentair bag systems
work independently of each other.
How the air bag system worksis
determined by predictingthe severity of
the accident,especially vehicle
deceleration or acceleration, and the type
of accident:
R
head-on collision
R
side impact
R
rollover
Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags
G
WARNING
R
Damaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchoringpoints
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-BenzCenter.
R
Air bags and pyrotechnic Emergency
TensioningDevices (ETDs) contain
perchloratematerial, which may require
special handlingand regardfor the
environment. Check your national disposal
guidelines. In California, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R
Air bags and ETDsare designed to function
on aone-time-only basis. An air bag or ETD
that has deployed must be replaced.
R
Do not pass seat belts over sharp edges.
They could tear.
R
Do not make any modification that could
change the effectiveness of the seat belts.
R
Do not bleach or dye seat belts,asthis may
severely weaken them. In acrash, theymay
not be able to provide adequate protection.
R
Do not make any modifications to the SRS
wiringorcomponents.
R
Do not modifyorremove any components
or partsofthe SRS.
R
Do not install additional trim material, seat
covers, badges, etc.tothe:
-
padded steering wheel boss
-
knee bag covers
-
front-passenger air bag cover
-
outer side of front seat bolsters
-
outer seat bolsters of the rear bench seat
backrest
-
roof frame trim
R
Do not install additional electrical/
electronic equipment on or near SRS
components and wiring.
R
Keep the area between the air bags and
occupantsfree of objects(e.g. packages,
handbags, umbrellas etc.).
R
Do not hang any objects such as coat
hangers on the coat hooks or the grab
handle above the door. These items may be
thrown around in the vehicle and cause
head and other injuries when the window
curtain air bag is deployed.
R
Air bag system componentswill be hot after
an air bag has inflated. Do not touch them.
R
Never rest your feet on the dashboard or
the seat. Always keep both feet on the floor
in frontofthe seat.
42
Occupant safety
Safety
R
Improper repairwork on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must thereforeonly be
performed by qualified technicians.
Consult an authorized Mercedes-Benz
Center.
R
For your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These are available from any
authorized Mercedes-Benz Center.
R
Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, Mercedes-Benz
strongly recommends that you inform the
subsequent owner that the vehicle is
equipped with SRS. Also, refer them to the
applicablesection in the Operator's Manual.
Air bags
Important safety notes
NEVERuse arearward facing child restraint
system on aseat protected by an ACTIVE AIR
BAG in front of it, DEATH or SERIOUS INJURY
to the CHILD can occur.
G
WARNING
Using unsuitable seat covers could restrictor
even preventdeployment of the air bags
integrated into the seats. Consequently, the
air bags cannot protectvehicle occupantsas
they are designed to do. In addition, the
function of the air bag deactivation system
could be restricted. This poses an increased
risk of injury or even fatal injury.
You should only use seat coversthat have
been approved for the respective seat by
Mercedes-Benz.
G
WARNING
The air bag parts are hot after the airbag has
been deployed. There is arisk of injury.
Do not touch the air bag parts. Have the
deployed air bags replaced at aqualified
specialist workshop as soon as possible.
G
WARNING
Air bags are designed to reduce the incidence
of injuries and fatalities in certain situations:
R
frontal impacts (driver's and frontpassenger frontair bags and driver's knee
bag)
R
side impacts(side impact air bags and
window curtain air bags)
R
rollover (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.
When the air bags are deployed, asmall
amount of powder is released.The powder
generally does not constitute ahealth hazard
and does not indicate that there is afire in the
vehicle. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. If you
have any breathing difficulty but cannot get
out of the vehicle after the air bag inflates,
then get fresh air by opening awindow or
door.
G
WARNING
In order to reduce the potential danger of
injuries caused during the deployment of the
front air bags, the driver and front passenger
must always be correctly seated and wear
their seat belts.
For maximum protection in the event of a
collision, you must always be in the normal
seat position with your back against the
backrest. Fasten your seat belt and make sure
that it is correctly positioned on your body.

As the airbag inflateswith considerable
speedand force, aproper seating position
and correctpositioning of thehands on the
steering wheel will help to keep you at asafe
distancefromthe air bag. Occupants who are
notwearing their seat belt, are not seated
properly or are too close to the air bag can be
seriously injured or killed by an air bag, as it
inflates with great forceinstantaneously:
R
sit with the seat belt fastened correctly and
in aposition that is as upright as possible
with your back against the backrest.
R
move the driver's seat as far back as
possible, still permitting proper operation
of vehicle controls. The distancefrom the
center of the driver's chest to the center of
the air bag cover on the steeringwheel
must be at least 10 inches (25 cm). You
should be able to accomplish this by
adjustingthe seat and steeringwheel. If
you have any difficulties, please contact an
authorized Mercedes-Benz Center.
R
do not lean your head or chest close to the
steeringwheel or dashboard.
R
only hold the steeringwheel on the outside.
Placing hands and arms inside the rim can
increase the risk and potential severityof
hand/arm injury if the driver frontair bag
inflates.
R
adjust the front-passenger seat as far back
as possible from the dashboard when the
seat is occupied.
R
occupants, especially children,should
never place their bodies or lean their heads
in the area of the door where the side
impact air bag inflates.This could result in
serious or fatal injuries should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt
properly and use an appropriately sized
infant restraint,toddler restraint or booster
seat recommended for the size and weight
of the child.
Failure to follow these instructions can result
in severe injuries to you or other occupants.
If you sell your vehicle, it is important that you
make the buyer aware of this safety
information. Be sure to give the buyer this
Operator's Manual.
If the air bags are deployed, you will hear a
bang, and asmall amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that there
is afire in the vehicle. The dust might cause
some temporary breathing difficulty for
people with asthma or other breathing
trouble. To avoid this, you may wish to get out
of the vehicle as soon as it is safe to do so.
You can also open the window to allow fresh
air to enter the vehicle interior. The 6 SRS
warning lamp lights up.
The air bag installation locations are
identified by the AIR BAG symbol.
The air bags are deployed if the air bag control
unit detects the need for deployment.Only in
the event of such asituationwill the air bags
provide their supplemental protection.
If the driverand front passengerdonot wear
their seat belts, it is not possible for the air
bags to provide their supplemental
protection.
In the event of other types of impacts and
impacts below air bag deployment
thresholds, the air bags will not deploy. The
driver and passenger will then be protected
to the extentpossible by aproperly fastened
seat belt. Aproperlyfastened seat beltisalso
needed to provide the best possible
protection in arollover.
Air bags provide additional protection; they
are not, however, asubstitute for seat belts.
All vehicle occupants must fasten their seat
belts regardless of whether your vehicle is
equipped with air bags or not.
It is important for your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective

Front air bags
Driver'sair bag : deploys in front of the
steeringwheel; front-passenger front air
bag ; deploys in front of and above the glove
box.
The front air bags increase protection for the
driver's and front passenger's head and
chest.
They are deployed:
R
at the start of an accident with ahigh rate
of vehicle acceleration or deceleration in a
longitudinal direction
R
if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R
independently of other air bags in the
vehicle
The release time of the front air bags is
dependent upon the use of the seat belt.
If the vehicle rolls over, the front air bags are
generally not deployed.
Your vehicle has adaptive, two-stage front air
bags. The air bag control unit evaluates
vehicle deceleration or acceleration in the
event of acollision. In the first deployment
stage, the front air bag is filled with part of the
total available propellant gas, thereby
reducing the risk of injury. If the air bag
control unit recognizes within afew
milliseconds that the vehicle is being braked
or accelerated faster than originally
predicted, the front air bag is filled with the
maximum amount of propellant gas available.
The deployment of the front-passenger front
air bag is also influenced by the weight
category of the front passenger, which is
determined by the Occupant Classification
System (OCS) (Y page 47).
The lighter the passenger-side occupant,the
higher the vehicle deceleration rate required
(predicted at the start of the impact) for
second stage inflation of the front-passenger
front air bag. In the second stage, the front
air bags are inflated with the maximum
amount of propellant gas available.
The front air bags are not deployed in
situations where alow impact severity is
predicted. You will then be protected by the
fastened seat belt.
The front-passenger front air bag will only
deploy if:
R
the system, based on the OCS weight
sensor readings, detectsthat the frontpassenger seat is occupied
R
the PASSENGER air bag OFF indicator lamp
on the center console is not lit
(Y page 47)
R
the air bag control unit predicts ahigh

G
WARNING
Usingunsuitable seat covers could restrictor
even preventdeployment of the air bags
integrated into the seats. Consequently, the
air bags cannot protectvehicle occupantsas
they are designed to do. In addition, the
function of the air bag deactivation system
could be restricted. This poses an increased
risk of injury or even fatal injury.
You should only use seat coversthat have
been approved for the respective seat by
Mercedes-Benz.
G
WARNING
Sensors to control the air bags are located in
the doors. Modificationsorwork not
performed correctly to the doors or door
paneling, as well as damaged doors, can lead
to the function of the sensorsbeing impaired.
The air bags might therefore not function
properly any more. Consequently, the air bags
cannot protectvehicle occupantsasthey are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door
paneling carried out at aqualified specialist
workshop.
You should only use seat coversthat have
been approved for your vehicle by MercedesBenz.The seat covers must have aspecial
tear seam for side impact air bags. Otherwise,
the side impact air bags cannot deploy
correctly and therefore cannot provide the
intended protection in the event of an
accident.
Front side impact air bags : and rear side
impact air bags ; deploy next to the outer
seat cushions.
When deployed, the side impact air bags offer
additional protection of the thorax for
occupants on the front seats as well as also
of the pelvis for the vehicle occupants on the
side of the vehicle on which the impact
occurs. However, they do not protect the:
R
head
R
neck
R
arms
The side impact air bags are deployed:
R
on the side on which an impact occurs
R
at the start of an accident with ahigh rate
of lateral vehicle deceleration or
acceleration, e.g. in aside impact
R
independently of the use of the seat belt
R
independently of the front air bags
R
independently of the ETDs
If the vehicle rolls over,the side impactair
bags are generally not deployed. Side impact
air bags are deployed if the system detects
high vehicle deceleration or acceleration in a
lateral direction and determines that side
impactair bag deploymentcan offer
46

additional protection to that providedbythe
seat belt.
Sideimpactair bags will not deploy in side
impacts which do not exceed the system's
presetdeployment thresholds for lateral
acceleration/deceleration.You will then be
protected by the fastened seat belt.
The side impact air bag on the frontpassenger side is not deployed in the
following situations:
R
OCS has detected that the front-passenger
seat is unoccupied.
R
the front-passenger seat belt is not
fastened.
The side impact air bag on the frontpassenger side will deploy if the frontpassenger seat belt is fastened, regardless of
whether the front-passenger seat is occupied
or not.

WARNING
Accordingtoaccidentstatistics, childrenare
saferwhen properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommendthat children be
placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriate infant
restraint,toddler restraint,orbooster seat
recommended for the size and weight of the
child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and Top Tether strap, or lower anchors
and Top Tether strap, fully in accordance with
the child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint,toddler restraint,orbooster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place achild in the frontpassenger seat:
R
Your vehicle is equipped with air bag
technology designed to deactivate the
front-passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of astandard appropriate
child restraint on the front-passenger seat.
R
Achild in arear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in acollision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to eliminate
this risk completely is never to place achild
in arear-facing child restraint in the frontpassenger seat. We therefore strongly
recommendthat you always place achild
48

in arear-facingchild restraint on the rear
seat.
R
If you install arear-facingchild restraint on
the front-passengerseat, make sure the
45 indicator lamp is illuminated,
indicating that the front-passenger frontair
bag is deactivated. Should the 45
indicator lamp not illuminateorgoout while
the restraint is installed, please check

Seat belts
Important safety notes
G
WARNING
The seat belt does not offer the intended level
of protection if the backrest is not in the
upright position. When braking or in the event
of an accident, you could slide underneath the
seat belt and sustain abdomen or neck
injuries, for example. This poses an increased
risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always make sure that the seat
is in the upright position.
G
WARNING
Seat belts cannot protect as intended, if:
R
they are damaged, extremely dirty,
bleached or dyed
R
the seat belt buckle is damaged or
extremely dirty
R
the EmergencyTensioning Devices or the
belt anchorage has been modified.
Damage caused to seat belts in an accident
may not be visible, e.g. by splinters of glass.
Modified or damaged seat belts can tear or
fail, for example in the event of an accident.
Modified EmergencyTensioning Devices may
be deployed unintentionally or fail to be
deployed when required. There is an
increased risk of injury, possibly even fatal.
Never modify seat belts, Emergency
Tensioning Devices, seat belt anchorages and
inertia reels. Ensure that seat belts are not
damaged or worn and are clean.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz.
The use of seat belts and infant and child
restraint systems is required by law in:
R
all 50 states
R
the U.S. territories
R
the DistrictofColumbia
R
all Canadianprovinces
Even where this is not required by law,all
vehicleoccupants should correctly fasten
their seat belts before starting the journey.

Proper use of the seat belts
G
WARNING
USE SEAT BELTS PROPERLY
R
Seat belts can only work when used
properly.Never wear seat belts in any other
way than as described in this section, as
that could result in serious injuries in the
event of an accident.
R
Each occupant should wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severityof
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver frontair bag, driver's side knee
bag, front-passengerfront air bag,side
impact air bags, windowcurtain air bagsfor
the side windows), Emergency Tensioning
Devices, seat belt force limiters, and front
seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags,
driver'sside knee bag and ETDs) and side
(sideimpact air bags, windowcurtain air

Safety
bags, and ETDs) impactswhich exceed
preset deployment thresholds and in
certain rollovers (window curtain air bags
and ETDs).
R
Never wear the shoulder belt under your
arm, across your neckoroff yourshoulder.
In afrontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck.Never pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet.
R
Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
abdomen, it could cause serious injuries in
acrash.
R
Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
R
Make sure the seat belt is alwaysfitted
snugly. Take special care of this when
wearing loose clothing.
R
Never use aseat belt for more than one
person at atime. Do not fasten aseat belt
around aperson and another person or
other objects at the same time.
R
Seat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distributeimpact forces.
The twisted seat belt against yourbody
could cause injuries.
R
Pregnant women should also alwaysuse a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
R
Place the seat backrest in aposition that is
as upright as possible.
R
Check your seat belt during travel to make
sure it is properly positioned.
R
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R
When using aseat belt to secure infant
restraints, toddler restraints, or children in
booster seats, alwaysfollow the child seat
manufacturer'sinstructions.
G
WARNING
Do not pass seat belts over sharp edges. They
could tear.
Do not allow the seat belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the seat belt.
Never attempt to make modifications to seat
belts. This could impair the effectiveness of
the seat belts.
Fastening seat belts
G
WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommendthat children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child. For additional information, see the
"Children in the vehicle" section.
Achild's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.

Belt warning for the driver and front
passenger
Everytime the engine is started, the 7
seat belt warning lamp lights up for six
seconds. It lights up regardless of whether
the driver's and front-passenger seat belts
have already been fastened. If the driver's
and front-passenger seat belts have already
been fastened, the 7 seat belt warning
lamp then goes out.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tonewill sound. This warning tonestops after
amaximum of six seconds or once the
driver's seat belt is fastened.
If after six seconds, the driver or front
passenger have not fastened their seat belts
and the doors are closed:
R
the 7 seat belt warning lamp remains lit
as long as the driver's or front-passenger's
seat belt is not fastened
and
R
if avehicle speed of 15 mph (25 km/h) is
exceeded, the 7 seat belt warning lamp
begins to flash. Awarning tone also sounds
withincreasing intensityfor amaximum of
60 seconds or until thedriver or front
passenger have fastened their seat belts.
If thedriver/frontpassenger unfasten their
seat belt while thevehicle is in motion,the
7 seat belt warning lamp lightsupand a
warning tone sounds again.
The warning tone ceases evenifthe driver or
front-passenger seat belt has still not been
fastened after 60 seconds. The 7 seat belt
warning lamp stops flashing but remains
illuminated.
After the vehicle comes to astandstill, the
warning tone is reactivated. The 7 seat
belt warning lamp flashes again if the vehicle
speed exceeds 15 mph (25 km/h).
The 7 seat belt warning lamp only goes
out if:
R
both the driver and the front passenger
have fastened their seat belts.

R
the belt tongue is engaged in the buckle on
each of the frontseat belts.
The ETDsonthe outside seats in the rear
compartment are triggered independently of
the lock status of the seat belts.
The ETDsare triggered depending on the type
and severityofanaccident:
R
in the event of ahead-on or rear-end
collision if the vehicle decelerates or
accelerates rapidly in alongitudinal
direction during the initial stages of the
impact.
R
in the event of aside impact if the vehicle
decelerates or accelerates rapidly in a
lateral direction on the side opposite to the
impact.
R
in certain situationswhere the vehicle rolls
over if the system determines that it can
provide additional protection.
If the ETDsare deployed, you will hear abang,
and asmall amount of powder may also be
released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicatethat there
is afire in the vehicle. The dust might cause
some temporary breathingdifficultyfor
people with asthma or other breathing
trouble. To avoid this, you may wish to get out
of the vehicle as soon as it is safe to do so.
You can also open the window to allow fresh
air to enter the vehicle interior. The 6 SRS
warning lamp lights up.
If the seat belt is also equipped with aseat
belt forcelimiter and this is triggered, the
forceexerted by the seat belt on the vehicle
occupant is reduced.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which take on apart of the deceleration force.
This results in the force exerted on the
occupant being distributed over agreater
area.

Child restraint systems
Important safety notes
G
WARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible.Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and top tether strap, or lower anchorsand
top tether strap, fully in accordance with the
child seat manufacturer's instructions.
Occupants, especially children,should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.

Children in thevehicle
Safety
Children can be killed or seriously injured by
an inflating air bag. Notethe following
important informationwhen circumstances
require you to placeachild in thefront
passenger seat:
R
Your vehicle is equipped withair bag
technology designedtodeactivate thefront
passenger frontair bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of astandard appropriate
child restraint on the front passenger seat.
R
For children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be activated.
Always make sure the 45indicator
lamp is illuminated, indicatingthat the front
passenger front air bag is deactivated.
R
Achild in arear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates in acollision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to
completely eliminate this risk is to never
place achild in arear-facing child restraint
in the front seat. We therefore strongly
recommendthat you always place achild
in arear-facing child restraint in abackseat.
R
If you must install arear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 45indicator
lamp is illuminated, indicatingthat the front
passenger front air bag is deactivated.
Should the 45indicator lamp not
illuminateorgoout while the restraint is
installed, please checkinstallation.
Periodically check the 45indicator
lamp while drivingtomake sure the 4
5 indicator lamp is illuminated. If the
45indicator lamp goes out or
remainsout, do not transport achild on the
front passenger seat until the system has
been repaired.
Achild in arear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates.
R
If you have to place achild in aforwardfacing child restraint on the front passenger
seat, move the seat as far back as possible,
use the proper child restraint
recommended for the age, size and weight
of the child, and secure child restraint with
the vehicle's seat belt according to the
child seat manufacturer's instructions.
G
WARNING
If the child restraint system is installed
incorrectly on asuitable seat, it cannot
protect as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There
is an increased risk of injury, possibly even
fatal.
Make sure that you observe the child restraint
system manufacturer's installation
instructions and the notes on use. Please
ensure, that the base of the child restraint
system is always resting completely on the
seat cushion. Never place objects, e.g.
cushions, under or behind the child restraint
system. Only use child restraint systems with
the original cover designed for them. Only
replace damaged covers with genuine covers.
G
WARNING
If the child restraint system is installed
incorrectly or is not secured, it can come
loose in the event of an accident, heavy
braking or asudden change in direction. The
child restraint system could be thrown about,

Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front,for vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road, weather and traffic
conditionsand maintain asafe distancefrom
thevehicle in front. Drive carefully.
i
The driving safety systems describedonly
work as effectivelyaspossible when there
is adequatecontactbetween thetires and
theroad surface. Pay particular attention
to theinformationregarding tires,
recommended minimum tire tread depths
etc.inthe "Wheels and tires" section
(Y page 312).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible.
ABS (Anti-lockBraking System)
General information
ABS regulatesbrake pressure in such away
thatthe wheels do not lock when you brake.
This allowsyou to continue steering the
vehicle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Important safety notes
i
Observe the "Important safety notes"
section for driving safety systems
(Y page 63).
G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems

are deactivated. Thereisanincreased danger
of skiddingand accidents.
Drive on carefully. HaveABS checked
immediately at aqualified specialist
workshop.
When ABSismalfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 239) and
displaymessages which may be shown in the
instrument cluster (Y page 208).
ABS works from aspeed of about5mph
(8 km/h), regardless of road-surface
conditions. ABS works on slippery roads,
even if you only brake gently.
Braking
X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking
situation is over.
X
To make afull brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
apulsing in the brake pedal.
The pulsating brake pedal can be an
indication of hazardous road conditions, and
functionsasareminder to take extra care
while driving.
BAS (Brake AssistSystem)
General information
BAS operates in emergency braking
situations. If you depress the brake pedal
quickly,BAS automatically boosts the braking
force, thus shortening the stopping distance.
Important safety notes
i
Observe the "Important safety notes"
section (Y page 63).
G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is arisk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheelsfrom locking.

Function
X
To activate/deactivate: activate or
deactivate the distance warning function in
the on-board computer (Y page200).
Vehicles with amonochrome

symbolappears in thestatus overview in the
multifunction display.
Vehicles with acolor multifunction
display:when the distance warning function
is deactivated, the æ symbol appears in
the assistance graphic in the multifunction
display.
The distance warning function can help you
to minimize the risk of afront-end collision
with avehicle ahead or reduce the effectsof
such acollision. If the distance warning
function detectsthat there is arisk of a
collision, you will be warned visuallyand
acoustically.Without your intervention, the
distancewarningfunction cannot prevent a
collision.
Starting at aspeed of around4mph
(7 km/h), the distancewarningfunction
warns you if you rapidly approachavehicle in
front.Anintermittentwarningtonewill then
sound, and the · distancewarninglamp
will light up in the instrumentcluster.
X
Brake immediately in order to increase the
distancefromthe vehicle in front.
or
X
Take evasiveaction provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving
conditions may also cause the system to
display awarning.
With the help of the radar sensor system, the
distancewarningfunction can detect
obstacles that are in the path of your vehicle
for an extendedperiod of time.
Fromaspeed of around40mph (70 km/h),
the distance warning function can also react
to stationary obstacles, such as stoppedor
parked vehicles.
If you approach an obstacle and the distance
warning function detects arisk of acollision,
the system will initially alert you both visually
and acoustically.
In particular, the detectionofobstacles can
be impaired if:
R
dirt on the sensors or anythingelse
covering the sensors
R
snow or heavy rain
R
interferencebyother radar sources
R
thereare strong radar reflections, for
example in parkinggarages
R
anarrowvehicle traveling in front, e.g. a

R
avehicle traveling in frontonadifferent line
relative to the center of your vehicle
Following damage to the frontend of the
vehicle, have the configurationand operation
of the radarsensor checked at aqualified
specialist workshop. This also applies to
collisions at low speeds where thereisno

As aresult, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay carefulattention to the traffic
situation and be readytobrake.
Due to the nature of the system, particularly
complicated but non-critical driving
conditions may alsocauseBrake Assist to
intervene.
Adaptive Brake Assist aidsyou in braking
during hazardous situations at speeds above
4mph (7 km/h) and uses the radar sensor
system to evaluate the traffic situation.
With the help of asensorsystem, adaptive
Brake Assistcan detect obstaclesthatare in
thepathofyour vehicle for an extended
period of time.
Should you approach an obstacle and
Adaptive Brake Assist has detected ariskof
collision, AdaptiveBrake Assist calculatesthe
braking force necessary to avoid arear-end
collision. Should youapply the brakes
vigorously,AdaptiveBrake Assist will
automaticallyincreasethe braking force to a
level suitablefor the traffic conditions.
X
Keepthe brake pedal depressed untilthe
emergency braking situation is over.
ABS prevents the wheelsfrom locking.
The brakes will work normallyagain if:
R
yourelease the brake pedal
R
there is no longerany dangerofarear-end
collision.
R
no obstacleisdetected in front of your
vehicle
Adaptive Brake Assist is then deactivated.
Up to vehiclespeeds of around 155 mph
(250 km/h),adaptive Brake Assist is capable
of reacting to moving objects that have
already been recognized as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due
to amalfunction in the radarsensor system,
the brake system remains available with full
brake boosting effect and BAS.
In particular, the detection of obstacles can
be impaired if there is:
R
dirt on the sensors or anything else
covering the sensors
R
snow or heavy rain
R
interference by other radarsources
R
there are strongradar reflections, for
example in parking garages
R
anarrow vehicle traveling in front,e.g. a
motorbike
R
avehicle traveling in front on adifferent line
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at aqualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
